Abstract
The utility mode relates to the technical field of potentiometers, in particular to a bakelite casing of a potentiometer. The bakelite casing of the potentiometer comprises a rotary shaft; the rotary shaft is connected with the casing of the potentiometer; a mounting positioning block and a substrate fixing block are arranged at the upper part of the casing of the potentiometer; a substrate is mounted on the substrate fixing block; and the casing of the potentiometer is made of bakelite. The casing of the potentiometer is manufactured by adopting the bakelite, since the bakelite has higher mechanical strength, favorable insulation performance, heat resistance and inoxidability, electricity leakage is avoided during the operation of the potentiometer, the production cost is low, and the use effect is favorable.
Description
Technical field
The utility model relates to the potentiometer technical field, especially a kind of bakelite shell potentiometer.
Background technology
The shell of present potentiometer adopts the manufacturing of common metal material, and such shell can cause the situation of potentiometer electric leakage in potentiometer work, and makes the quality of potentiometer be unfavorable for more greatly installing, and manufacturing cost is high.
The utility model content
The deficiency that adopts metal material to make in order to overcome existing potentiometer shell, the utility model provides a kind of bakelite shell potentiometer.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of bakelite shell potentiometer, comprise rotating shaft, described rotating shaft connects the potentiometer shell, described potentiometer shell top is provided with installs locating piece and substrate fixed block, on the described substrate fixed block substrate is installed, described potentiometer shell adopts the bakelite manufacturing.
The beneficial effects of the utility model are, the shell of this bakelite shell potentiometer adopts the bakelite manufacturing, because bakelite has higher mechanical strength, good insulating properties, thermal endurance, corrosion resistance, so just can avoid potentiometer the situation of electric leakage in work, to occur, and production cost is low, and result of use is good.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Among the figure 1, rotating shaft, 2, substrate, 3, locating piece is installed, 4, the substrate fixed block, 5, the potentiometer shell.
Embodiment
Structural representation of the present utility model such as Fig. 1, a kind of bakelite shell potentiometer, comprise rotating shaft 1, described rotating shaft 1 connects potentiometer shell 5, described potentiometer shell 5 tops are provided with installs locating piece 3 and substrate fixed block 4, on the described substrate fixed block 4 substrate 2 is installed, described potentiometer shell 5 adopts the bakelite manufacturing.
This bakelite shell potentiometer adopts the bakelite manufacturing with potentiometer shell 5, because bakelite has good higher mechanical strength, good insulating properties, thermal endurance, corrosion resistance, so just guaranteed the situation that potentiometer can not occur leaking electricity in work, so just can guarantee the work safety of potentiometer, result of use is good.
